Tech Bundle

Singapore Battery Consortium

With rapid research advancements in battery technologies, lithium-ion batteries have become an indispensable part of modern life: they provide a reliable power source for portable electronic devices such as mobile phones and laptops, and have led to transformative technologies like electric vehicles. Continued research and development has yielded breakthroughs in new battery materials and chemistries with enhanced performance and lifespan, as well as system level improvements. In recent years, much attention is also given to repurposing batteries for new applications and recycling of end-of-life batteries. The Singapore Battery Consortium Tech Bundle features a curated list of technologies for enterprises to discover new collaboration and co-creation opportunities.

Ultrathin and Flexible Printed Batteries for Smart Labels, IoT and Medical Wearables
The technology offer presents ultrathin, flexible, safe and high-performance zinc batteries. The patented High Conductivity Polymer Electrolyte (HCPE) is stable, rechargeable, printable to a solid-state. Therefore, it does not need a sealed container. Furthermore, the HCPE allows for low internal resistance, and hence maximizes power. As the chemistry is based on zinc rather than lithium, it avoids the safety issues that have plagued many lithium technologies, such as soil and air contamination when extracting lithium. The expensive casing could be another issue for lithium technology. Since the batteries are printed, they can be produced in most shape and size to meet specific project design needs. This technology offer can provide a safe, disposable and label-like power source for logistics smart tags, data loggers and medical patches. It is making inroads to becoming a de facto green battery chemistry alternative as more product designers and customers demand safer and more sustainable electronic products.

Scalable, Cost-effective Calorimeter for Thermal Monitoring of Batteries
Battery cells must be tested for performance and operational reliability from the design phase to the production process, to safeguard its safety, reliability and cost. As batteries are prone to temperature-related issues, like overheating and overcharging, there can be extreme spikes in temperature known as ‘thermal runaway’. In order to evaluate the thermal performance of the battery, calorimetric testing can produce data that indicates defects at an early stage and thus help to predict a ‘thermal runaway’ at a later stage.  A German research institute has developed a modular, scalable calorimeter to measure the thermal data of batteries of diverse cell sizes. The scalable system is suitable for applications in thermal monitoring from new module designs to new battery materials and quality assurance. The modules are currently in use at the research institute and this calorimeter has German utility model protection. The research institute is searching for partners for the joint further development in research cooperation agreements or for partners interested in a direct license.
